Boot fails for cljs task (can't locate boot_cljs__init.class) on Windows 10 #192

kirill-gerasimenko · 2018-05-21T13:38:53Z

Hi,

I'm going through https://github.com/magomimmo/modern-cljs/blob/master/doc/second-edition/tutorial-01.md tutorial and at the stage after defining dependencies and calling boot -h I'm getting the exception below.

I'm on Windows 10 (1709), using JDK 8 (1.8.0_172), boot is installed via Chocolatey.
I've reinstalled java, cleaned ~/.m2 and ~/.boot directories - exception is still there.

Please advise.

I've tried on the latest Manjaro Linux - and it has the same error.

danielsz · 2018-05-22T22:22:57Z

My guess is that you're missing the require in build.boot.

(require  '[adzerk.boot-cljs :refer [cljs]])

kirill-gerasimenko · 2018-05-23T05:14:43Z

Actually I do have it, here is the full contents of build.boot:

(set-env!
 :source-paths #{"src/cljs"}
 :resource-paths #{"html"}

 :dependencies '[[adzerk/boot-cljs "2.1.4"]])

(require '[adzerk/boot-cljs :refer [cljs]])

For additional data, I also have this issue. I'm on Mac OSX, Clojure 1.9.0, Java 8, boot-cljs 2.1.4, Clojurescript 1.10.312.

EDIT: this setup works if I swap Clojurescript 1.10.312 for 1.9.946.

@ckampfe I'm having the same problem as you, right down to the stack trace. Maybe it's due to those Classpath conflict errors?
